TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 260,105, dated June 27,1882. Application filed August 31, 1881. (No model.)

To all whom it may concern: 4

Be it known that I, GEORGE LOGKHART, of Tarrytown, county ofWestchester, and State of New York, have invented certain new and usefulImprovements in Tobacco- Pipes, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The object of my invention is to produce a neat, cheap, and durable pipeor holder for tobacco for smokers use, which, while it is in the generalform of a ci gar,ma y be loaded or charged with loose tobacco, after themanner of an ordinary bowl-pipe, and the tobacco, as the burningprogresses, be forced continuously toward the outer end of the device bymechanism which may be conveniently operated, and which will occupy butlittle spacein the tobacco-chamber. To accomplish this theinventioninvolves certain novel and useful arrangements or combinationsof parts and peculiarities of construction, as well as principlesofoperation, all of which will be herein first fully described,-andthenpointed out in the claims.

In the accompanyin g drawings, forming part of this specification,Figure 1 is a perspective view intended to illustrate the generalexterior form of a tobacco-pipe constructed and arranged in accordancewith my improvements. Fig. 2 is an axial section of the pipe, showingthe piston as retracted or in position to admit of the full charging ofthe tobacco-chamber. Fig. 3 is a view similar to Fig. 2, but showing thepiston as forced out toward the mouth of the tobacco-chamber. Fig. 4 isan axial section of a pipe, showing a slightly-modified means ofcoupling the screws with the mouth-piece, but within the scope of myinvention. Figs. 5, 6, 7, and 8 are end views, indicating some of themany forms which may be given the interior of the tobacco-chamber andthe piston in order to prevent the latter from turning while beingforced forward or backward.

In all these figures like letters of reference, wherever they occur,indicate corresponding parts.

A is the main shell,made to approximate the form of a cigar and intendedto contain the tobacco for smoking. This shell may be made of anydesired size and of any material suitable for the purpose, as metal,clay,paper,- rubber,

wood, papier-mach, plaster, and various materials not necessary toenumerate.

Within the shell A is a piston, B, intended to be capable of beingforced forward, so that as the tobacco is burned away the remainder ofthe charge is forced toward the forward end of the shell and the ashesforced out.

To move the piston back and forth I employ any convenient number ofscrews, asOD E, engaging one with the other,and having one section, as0, attached to the piston,and the last section, as E, connected with arevolvingend piece, as at F.

The end piece, F, is connected with the shell by any convenient form ofjoint, substantially as indicated at a, which joint will allow the endpiece to revolve, but will not. allow it to move in the direction of theaxis of the shell.

The section E beingconnected with end piece,

F, it is plain that by turning the end piece the screws may be made ,toadvance or retract the piston, the latter being prevented from turningwithin the tobacco-chamber. I make the screws in short sections, so thatwhen the piston is drawn back into the shell the working mechanism willoccupy but little room. Of course the shorter the sections the less thespace required to accommodate them, and they should be made suflicientin number, so that when fully extended they will carry the piston nearto the outer end of the shell. The section 0 is headed in some suitablemanner, so that it cannot be forced out of the adjacent section, D, andso on for the remaining sections.

To prevent the piston from jamming up against the section D, so that itwould be hard to turn said section,any suitable washer, asat b, may beapplied, and other washers may be applied at other points of contact, ifdesired.

The shell is preferably perforated near the end, as plainly shown atFigs. 1, 2, and 3, so as to insure a good supply of air for the burningtobacco within the shell but the perforations might be omitted, as inFig. 4,. if they be found unnecessary.

Instead of making the perforations in thematerial of the shell,theinvention contemplates the employment of a tip or burning-piece ofnon-conducting material-such as clay, &c.- in which the perforations maybe made, and in which, during ordinary careful use of the pipe, the firewill be located. The piston is intended to be perforated for the passageof smoke, and the sections of the screw may be likewise perforated; butif the piston be made enough smaller than the tobacco-chamber, and theconnection of the last screw-section with the revolvin g end piece bemade open, ample passage for smoke will be insured.

Insteadot'employing the re\ *olvingendpiece, F,witl1its attachedmouth-piece G,as shown in Figs.2 and 3, the screws may beconnected withthe month-piece G directly and this in outh-piece made to revolve on theend of the shell,which is solid from the joint with G to the outer end,as shown in Fig. 4.

A convenient means of attaching the mouthpiece is shown at 0, wherein asimple metallic band unites a head on the mouthpiece with a similar beadon the end of the shell.

For the mouth-piece bone, amber, or other suitable material may beemployed.

The piston may be prevented from turning within the shell by giving anynumber of forms to the interior or bore, (except circular.) Forinstance, the tobacco-chamber may be made square or rectangular, asindicated in Fig. 5, or it may be made with flattened sides, as in Fig.6, or with grooves, as in Fig. 7, or with ribs, as in Fig.8,the pistonbeing made to conform thereto in general outline. A variety of ways foraccomplishing the same object will suggest themselves, those given beingonly a few of the most convenient and easy methods.

The pipe thus constructed is operated as follows: The piston isretracted by turning the end piece or mouth-piece. The tobacco-chamberis then charged with cut tobacco (long-out tobacco is best, but anyother may be used) and the charge fired. As the tobacco is consumed thepiston is forced forward by turning the shell upon the end piece whilethe latter is held stationary between the teeth. This keeps the fire atthe outer; extremity of the shell and prevents the accumulation ofashes. When the charge is entirely. consumed the remaining ashes may beknocked out and the pipe is cleaned, ready to be put in the pocket, orready to receive another charge.

The pipe so constructed and arranged is sim- 5o ple, comparativelyinexpensive, and may be carried in the pocket, likean ordinarycigarorcigarholder. It has the advantage of being capable of use like a cigar,while out tobacco may be employed in it, as in an ordinary bowl-pipe,and it is found to admirably answer the purposes and objects of theinvention, as previously stated.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a pipe of the character herein set forth, the main exteriorshell,therevolving end piece connected with said shell, the movablepiston fitted to the interior bore, said piston being perforated, asexplained, and carrying a screwthreaded section attached to and turningwith the revolving end piece, and the washer b, all combined andarranged to operate substantially as shown and described.

2. The herein-described tobacco-pipe, composed of the main shell, therevolving end piece mounted thereon, the short screw-sections 0 D E,located in the tobacco-chamber, and the piston B, connected with the endpiece and prevented from turning, substantially as shown and described.

3. In a tobacco-pipe of the character herein set forth, the main shellA, having perforations at the outer end, the section 1*, and monthpieceG, perforated piston B, fitting the interior bore, screw-threadedsections O D E, and washer I), all combined and arranged to operatesubstantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.
